Multipoint-to-Multipoint Connection
A Multipoint-to-Multipoint Connection is a collection of associated ATM VC or
VP links, and their associated nodes, with th e following properties:
• All Nodes in the connection, called endpoints, serve as a Root Node in a
Point-to-Multipoint connection to all of the (N-1) remaining endpoints.
• Each of the endpoints on the connection can send information directly to any
other endpoint, but the receiving endpoint cannot distinguish which of the
endpoints is sending information without additional (e.g., higher layer)
information.
Multipoint-to-Point Connection
A Point-to-Multipoint Connection may have zero bandwidth from the Root node
to the Leaf Nodes, and non-zero return bandwidth from the Leaf Nodes to the Root
Node. Such a connection is also known as a Multipoint-to-Point Connection. Note
that UNI 4.0 does not support this connection type.
MUX
Multiplexer: Electronic equipment which allows two or more signals to pass over
one communications circuit. That (circuit) may be a phone line, a microwave
circuit, a through-the-air TV signal. That circuit may be analog or digital. The re are
many multiplexing techniques to accommodate both.
N
Native Address
An address that matches one of a given node's summary addresses.
NC
Network Connection
NDIS
Network Driver Interface Specification: Refer to 3COM/Microsoft, LAN Manager:
Network Driver Interface Specification, October 8, 1990.
NE
Network Element: A system that supports at least NEFs and may also support
Operation System Functions/Mediation Functions. An ATM NE may be realized as
either a standalone device or a geographically distributed system. It cannot be
further decomposed into managed elements in the context of a given management
function.
